RAIL-CHECK.

Application le. October 23, 1913.

To all whom it may concern:

Be it known that I, DANIEL Ii. BRAINE, a citizen of United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Rail-Checks, of which the following is a specification.

This invention relates to improvements in rail checks, and has for its object to provide an improved device to prevent creeping of a rail after the same has been set in final position.

I am aware that many forms of devices have been constructed in the endeavor to attain this ob] ect, but am not aware of any which accomplishes this purpose by utilizing an elliptical check provided with roughened surfaces which coact with the rail base as in the case of my device.

An advantage of my device is that I am enabled to fit the same to individual spikes previous to their being driven and there is no danger of their being displaced thereafter. Furthermore, they operate automatically and do not require adjustment from time to time. This and other objects will be set forth and shown in the following specification and accompanying drawings, in which;

Figure 1 is a side elevation of a spike showing my device applied thereto;

Fig. 2 is a horizontal section taken on the line 2 of Fig. 1;

Fig. 3 is a side elevation of my device as applied to a driven spike;

Fig. et is a view along the line L1 of Fig. 3;

Fig. 5 is a transverse vertical section through a rail and supporting means showing my device utilized in connection with a. metal frame or tie-plate; and

Fig. 6 is a plan view of the same partially in section.

Like numerals refer to like elements throughout the drawings.

In the form shown in Figs. 1 and 2, 10 designates generally a rail having the flanged base 11 supported upon a tie 12. The screw spike 13 of conventional con struction, is shown with the head 13a thereof retaining the rail base 11 in contact with the tie 12. My improved rail check is designated by numeral 15 and comprises an Spcccaton of Letters Patent.

approximately elliptical collar or plate apertured at 15ZL to permit its iitting on the neck or shank of the spike 13 so as to freely rotate upon the same. The periphery of the check 15 is roughened or sharply corrugated, as indicated by numeral 15b. I/Vhen the device is assembled, it is placed upon the spike and the latter is driven or screwed to place, as shown in Figs. 1 and 2 with the minor axis at right angles to the longitudinal axis of the rail base, so that the portion of least diameter is in contact with the edge of the rail base 11. It will be apparent that upon commencement ofthe creeping or longitudinal movement of the rail, the base being in contact with the roughened surface 15b will cause a partial rotation of the check 15 so as to cause a wedge action to ensue, due to the increasing diameter of the portion of the rail check between the spike 13 and the rail base 11. This wedge action serves to restrain the further creeping of the rail and consequent-ly is caused automatically, as will be apparent upon initial movement of the rail. Furthermore, the collar or check 15 being in contact with the surface of the tie or the like on both sides of the spike 13 will serve to resist or partially resist over-turning or bending of the spike.

In the form shown in Figs. 3 and 4, my check is provided with an enlarged bore or aperture 15c in which is fitted a bushing 16 of brass or the like, the same being provided with a square centrally located aperture 16a to t over and engage the driven spike 13. It will be apparent that the action of the rail check is similar in this form to its action in the form shown in Figs. 1 and 2, the bushing 1G being held against rotation by the non-circular cross-section of the drive spike and the check proper being permitted vto rotate upon said bushing.

In Figs. 5 and 6 I have shown a device as applied to the form of rail supporting and fastening means wherein the rail is supported upon a block 2O and is held against lateral movement by a metal frame 21 supported upon the said block 20. This metal frame 21 is provided with the spiking slots or apertures 21a and a flange or shoulder 21b extends therearound. vWhen screw spikes are utilized with this form of plate this Cil flange or shoulder 2lb may act as the reinforcement for the head of the spikes to prevent outward bending thereof, as shown in F ig. 5. This flange or shoulder 21b is preferably of suicient height to contact with the spike head when the latter is in holding position with respect to the rail so as to prevent cramping or binding of the check rail and irst named member to prevent creeping of said rail.

et. 1n combination, a rail, a frame member adapted to restrain lateral movement of said rail, a rail check coacting with the lateral edge of the base of said lrail and supported above said frame member to prevent creeping of said rail.

from possible contact with the undersidein5.- 1n combination, a rail, a frame meinof the spike head. A rail check is carried upon one or more of these spikes, as shown in Fig. 6, wherein l have shown two diagonally opposed checks. The metal frame 21 is preferably extended outwardly of the ianges or shoulders 2lb to contact with one side of the spike shank and at the same time it furnishes a seat for rail checks 15. rlhe inner periphery of each shoulder or Hange 2lh is spaced as clearly shown in Fig. 6 so as to be slightly out of contact with the periphery of the check l5, the latter, however, being in contact with the rail base in its initial position as in the construction described and shown in Figs. 1 and 4. Partial rotation of this rail check 15, however, will cause the same to engage the inner periphery of the shoulder or iiange 2lb which receives the stress transmitted by the wedge action of the check l5 thereby relier/'ing the spike from the same. The portion of the metal frame around the spiking apertures designated by numeral 21C extends partially around and preferably contacts with the body of the spike as clearly shown in Figs. and 6 of the drawings, so that side stress received by the spike from the rail is transmitted to the metal frame and is thereby equally distributed between all spiking members.

1t will be apparent that 1 have provided a new and simple form of rail check which will operate automatically upon initial creeping7 of the rail and which is easy to place in position and inexpensive to manufacture. It is obvious that my device is susceptible of many modifications and changes, and I do not wish to be restricted to the form shown and described, beyond the scope of the appended claims.
